Summary

The Canadian Food Inspection Agency (CFIA) confirmed detection of the pathogen Ralstonia solanacearum race 3 biovar 2 (Rs R3bv2) in a symptomatic geranium (Pelargonium sp.) sample taken from an Ontario greenhouse. The plants were already under official control at the premises to prohibit movement pending inspection and disposal in response to earlier reports of Rs R3bv2 associated with imported geranium from Guatemala. Rs R3bv2, commonly referred to as Southern wilt, bacterial wilt, and brown rot of potato, causes a wilt disease in several important agricultural crops such as potatoes, tomatoes, peppers, and eggplant. The geranium sample that tested positive was from a Fantasia ‘Pink Flare’ variety geranium, which had been imported from a production facility in Guatemala. The grower is cooperating fully in the investigation, has destroyed all Fantasia ‘Pink Flare’ on the premises and is carrying out disinfection in accordance with CFIA instructions. CFIA has inspected all greenhouses that received Fantasia ‘Pink Flare’ geranium cuttings and liners, collecting trace-forward information, and destroying all Fantasia ‘Pink Flare’ geraniums and co-mingled and exposed host and non-host plants. Cleaning and disinfecting the greenhouses will follow approved methods.
